| Summary | Real-time long-term monitoring of the electric field and geomagnetic field can be used not only to study the induced currents generated by geomagnetic storms but also to investigate the electrical structure of the mantle. We developed ultra-stable non-polarizing electrodes and magnetotelluric instruments equipped with 4G data transmission. Since December 2023, we have been conducting magnetotelluric monitoring in the North China Craton region. Currently, 40 measurement sites have been operating stably for six months, measuring the G5 geomagnetic storm and induced electric field in May, 2024. We estimated the magnetotelluric impedance in the periods of 10-105 seconds, which is expected to invert a three-dimensional conductivity model of the deep mantle in the North China Craton. |
